GAS-BURN ER.

SPECIFICATION forming part of Letters Patent No. 364,101, dated May31,1887.

Application filed August 5, 1886. Serial No. 210,079. (No model.)

bustion of the gas is enhanced, an intenseheat obtained, andobjectionable accumulations of unconsumed carbon prevented.

In the accompanying drawings, forming part of this specification, Figure1 is a vertical sectional elevation of a burner embodying ourimprovements. Fig. 2 is a sectional plan of the construction shown inFig.1.

Similarletters of reference indicate similar parts in the respectivefigures.

Heretoforein burning natural and other gases imperfect combustion hasensued,by reason of an incomplete mixing or commingling of the air andgas, this difficulty resulting in the deposition of unconsumed carbon inthe burner andthe obstruction of the passages therein. By ourimprovements we obviate the difficulties noted.

A refers to a central tube, around which are mounted a series ofconcentric walls or partitions, B B B inclosing annular spaces orchambers cl d d, the tubeA forming a central passage, a. The upperpart'of said tube A extends up beyond the edges of the walls orpartitions B B B", where it is extended laterally to form a deflector,C. It will be seen, Fig. 1, that the first annular space or chamber, dthat is to say, the one adjacent to the central tube, A--is provided atits lower end with openings 0", communicating with the pipe F. The spaceor chamber (1 is closed at its lower end at c, and has an opening in thewall or partition B connecting with the gas-supply pipe (Z. The outerspace or chamber, (1 is the shortest in length, and communicates withthe pipe F by means of the openings 6.

Our improved burner being especially designed for application to stovesand heaters of various kinds using natural or other gas as a fuel, Fig.1 shows the position of the burner relative to the grate surface D. Theair is sup plied through the pipe F, which incloses the lower ends ofthe vertical partitions B B B The front end of the pipe F communicateswith the atmosphere through the furnace-front G, and said end is coveredby a gauze shield or perforated guard, g. The gas-supply pipe d passesup through the grate D to the burner. In existing forms of gas-burnersfor stoves great danger is experienced when the gas is cut off, whichgenerally causes the flame to flash back and out of the air-pipe with aloud report. By placing the gauze shield or'perforated guard g in theair-pipe the flame will be extinguished when it reaches said shield orguard.

In operation the air can only reach thepoint of combustion by passingthrough the perforated guardg. The gas is admitted to the annularchamber or space d, andissucs from the upper end thereof, where itstrikes the under side of the deflector O. The air, traveling in thesame direction as the gas, passes up the an-- nular passages d d,strikes the deflector, and completely mixes with the gas. Combustion ofthe mixed air and gas is carried on beneath the deflector, and a lateralspread being effected by the deflector, a steady and uniform burning isproduced and an undue concentration of heat prevented. The air alsopasses up the central passage, (1, of the tubeA andIcomes in contactwith the flame on the upper side of the deflector G, and thus causes amore perfect combustion. This additional current of air, mixing with theflame above the deflector, .is particularly effective in burning naturalgas. Natural gas is usually supplied under a very great pressure, andlarge quantities of it therefore pass off unconsumed, owing to theinsufficiency of the supply of atmospheric air necessary to rendercombustion perfect. plying the additional current of air, as described,the combustion is rendered more perfect, and hence a greater degree ofheat is attained.

\Ve claim 1. In a burner for gas, the main air-tube, the gas-supply pipelocated within and passing through said air-tube, and partitions form-'ing annular spaces for conveying air and gas below the deflector, theair spaces communieating with the main airtube and being located one oneach side of the gasspace, com
